REVERSIBLE DISK PLOW- SPECIFICATION forming part of Letters Patent No. 785,963, dated March 28, 1905. Application filed May 5, 1904. Serial No. 206,542.

To all whom, it may c0noern:

Be it known that I, EPHRAIM MANEs, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee,'have invented a new and useful Reversible Disk Plow, of which the following is a specification.

This invention relates to disk plows of that class which are capable of being reversed, so that they may be used either as right-hand or as left-hand plows, as the case may demand, and it has especial reference to that class of reversible disk plows in which a suitably-constructed frame carries a pivotally-mounted disk-carrying standard, said standard being capable of being rotated upon its axis within certain predetermined limits, whereby the eventual position of the disk shall be determined.

The present invention has for its prime object to provide a device of the class referred to'in which the reversal of the disk or diskcarrying standard shall be accomplished by the direct pull in a forward direction of the team attached to the implement.

Another object is to provide adjustable stop means of an improved character.

Still another object is to provide a springactuated and pivotally mounted scraper which shall be reversible with the tongue, so as to be in position to cooperate with the disk in any position assumed by the latter.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being understood, however, that no limitation is necessarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modifications which come fairly within the scope of the invention, but which may be resorted to without departing from the spirit or sacrificing any of the advantages of the same.

In said drawings, Figure 1 is a top plan view showing a plow constructed in accordance with the principles of the invention in position for operation. Fig. 2 is a top plan view in which the full lines represent the device as it appears after the tongue and subbeam have been swung around prior to reversing the direction of travel and in which the dotted lines represent the positions assumed by the various parts after a start has been made. Fig. 3 is a sectional view taken on the line 3 3 in Fig. 2, but showing the tongue in a position intermediate the positions shown in Figs. 1 and 2. Fig. 4 is a perspective detail view. Fig. 5 is a sectional detail view of a portion of the subbeam and tongue. Fig. 6 is a perspective detail view of the rear end of the tongue and the scraper. Fig. 7 is a side elevation of the device complete.

Corresponding parts in the several figures are indicated by similar numerals of reference.

The frame 1 of the improved plow is constructed on the lines of the arc of a circle and is provided with radial arms 2 2, converging with each other at a point which is concentric with the body 1 of the frame. This central point affords a pivotal point for the upper end of a standard 3, carrying a disk 4., said standard and disk being of ordinary or any approved construction.

Firmly secured upon the standard 3 above the frame-arms 2 2 is an arm 5, one end of which is extended in the direction of the segmental portion of the frame and is disposed in the path of a pair of slotted stop-lugs 6 6, which are connected adjustably with the radial arms 2 of the frame, said stop-lugs being provided for the purpose of limiting the movement of the arm 5. The opposite end of the latter supports a tongue 7 which is pivotally connected therewith.

8 designates a subbeam which is pivotally mounted upon the disk-carrying standard above the arm 5 and which is provided at its outer end with a hook 9, engaging under the segmental portion of the frame 1. Said subbeam is also provided at or near its outer end with a loop 10, through which the tongue 7 extends and is freely slidable. A seat-supporting bar 11 is likewise connected with the subbeam, from which it extends upwardly and rearwardly, carrying a seat 12, which is of ordinary construction.

The ends of the segmental portion of the frame are provided with divergent brackets 13, having vertical perforations in which are pivotally mounted shanks 14, having spindlecarrying cranks 15, pivotally connected therewith and capable of adjustment with relation thereto by means of the toothed quadrants 16 and levers 17, having spring-actuated pawls or dogs engaging said toothed quadrants. The spindles 18, carried by the cranks 15, support the ground-engaging wheels 19, which by the means described may be raised or lowered for the purpose of lowering or raising the frame of the machine, as may be required. Brackets 20, supporting a similarly-mounted land-wheel 21, are connected with the under side of the segmental portion of the frame. It will be observed that the land-wheel, as well as the furrow-wheels, being mounted upon swiveled caster-stems the said wheels will readily adapt themselves to any direction in which draft may be exercised upon the device. This feature, however, is well known in various forms of plows and is not herein claimed.

The stems or shanks 14:, which support the furrow-wheels, are provided with divergent arms or brackets 22, disposed in the path of the tongue 7 and provided with set-screws 23 or other equivalent means which shall act as stops for the tongue to check the lateral movement of the latter and also to prevent the wheels carried by the shanks 14 from moving beyond a predetermined point previously fixed by adjustment of the screws 23.

Pivotally connected with the arm 5 at or near the point where the tongue 7 is pivotally connected with said bar and preferably upon the pin or bolt 24, which connects the tongue 7 with the arm 5, is an arm 24, carrying a scraper 25, which is approximately spoonshaped, so that it shall be adapted to cooperate with the surface of the disk 1 in any position which may be assumed by the latter. The portion 25 of the arm 24, which pivotally engages the pin or bolt 24, is preferably interposed between the arm 5 and the tongue 7. The arm 24 is provided with springs 26, permanently connected therewith and having upturned ends 27, which rest against opposite sides of the tongue 7, thus affording means whereby the scraper shall be automatically held in contact with the face of the disk when the latter is in operative position. The intermediate portions of the springs 26 lie against opposite sides of that portion 25 of the arm 24 which is interposed between the arm 5 and the tongue 7, so that when the latter turns upon its pivot the arm 24 will be carried with it by the action of the springs, which latter when the scraper comes into contact with the plow-disk will flex, so as to hold the said scraper resiliently in contact with the plowdisk. The springs being thus disposed will obviously not obstruct or in any wise interfere with the free movement of the parts 5, 7, and 24 with relation to each other.

The operation of this invention may be briefly described as follows: The normal operative position of the device will be clearly understood by reference to Fig. 1, in which it will be seen that the tongue 7 is practically in alinement with the furrow-wheels 9 10 and the land-wheel 21, the disk 4 being disposed at the proper angle for efficient work, where it is retained by the extremity of the arm 5 bearing against one of the adjustable lugs 6, which have been previously adjusted to determine the angle at which the disk L shall be held with relation to the line of progress. When it shall be desired to reverse the plow at the end of a row, the team, which is attached to the extremity of the tongue, is simply started to walk around the landside of the plow, the subbeam 8 turning upon the fulcrum afforded by the upper end of the diskcarrying standard, while the tongue 7 turns upon the fulcrum formed by its pivotal connection with the arm 5, this being made possible by the fact that the tongue is slidingly connected with the subbeam by means of the loop 10. The subbeam being disposed above the arm 5 readily clears the adjusting-blocks 6, which are disposed in the path of said arm, and' the tongue, if mainly disposed above the suhbeam, will encounter no hindrance to its turning. It will be noted that while the tongue and subbeam are being reversed the disk remains stationary in the ground. The related parts are made of proportions which will enable the tongue to clear the disk. As the tongue is reversed it carries with it the scraper 25, as will be readily understood. The limit of the movement of the tongue is reached when the latter passes into engagement with the stop members 28 in the divergent arms 22 of the shank of the furrow-wheel, which was previously the rear one, but which when the reversal takes place becomes the front wheel. The tongue striking against one of said stop members will induce the shank 14: to partially turn in its bearings until the other stop member comes in contact with the tongue, thus opposing the further movement of the latter. It will now be seen that by simply starting the team in a forward direction the draft of the tongue will be exerted upon one end of the arm 5, which latter is rigidly connected with the disk-carrying standard, the latter will be oscillated in its bearing in the frame, and the position of the disk will be properly reversed, the movement being checked when the opposite end of the arm 5 encounters the stop member 6. As the draft is continued the land-wheel and the rear furrow wheel will readily swing into alinement with the line of draft, and the plowing may now continue until the opposite end of the field is reached and it again becomes necessary to reverse.
